POLE PUSHER.

Application filed June 28,

To all 'Lo/wm t may concern:

Be it known that I, PHrLir J. Hannan, oBloomield, in the county ofGreene and State of Indiana, have invented certain new and usefulImprovements in Pole Pushers; and I do hereby declare the following tobe a Jfull, clear, and exact description of the invention, such as willenable others skilled in the art to which it appertains to make and usethe same.

My invention provides improved means for raising posts and poles andespecially for correcting the position of wire supporting poles whichare leaning or out of proper alinement.

Figure 1 shows the pusher in operative position. Figure 2 is a crosssection on line 2 2, Figure 1. Figure 3 is a detail.

The invention comprehends two telescoping sections, a lower sectionanchored to the ground, and an upper section to engage the pole, thelower section having means Jfor advancing the upper one.

The lower section is made in accordance with the disclosures of LettersPatent 1,374,- 653 issued to me April 12, 1921, for lifting jack. Asthere shown, as well as in the accompanying drawing, it comprises a baror standard 1 having a longitudinal series lof holes 2 extendingentirely through its thickness. These holes are to receive pins 12 and18 carried, respectively, by runners 3, 4, movable on the bar 1. A lever5 is pivoted to runner 4 and has a pitman 7 pivotally connected withrunner 3, whereby the two runners are alternately movable on the bar,the pins 12 and 18 being alternately pressed into holes 2 of bar 1 bysprings coiled upon them, as the runners move lon-V gitudinally of thebar consequent upon the action of lever 5.

In the present case VI have shown the bar terminating at its lower endin a channel iron 22 having its flanges to the ground and formed in itsbodyportion with al hole large enough to engage the end ofthe bar butnot large enough to permit it to pass entirely through.

The bar 1 is I-shape in cross section. The runner 4 encloses the bar andat its 1922. Serial No. 571,486.

top projects laterally well beyond the bar and forms an eiective seat.23.

24 is the upper section of the device. It is shown as a cylindertelescoping the bar and resting upon the seat aorded by the runner 4. Atits outer end this cylinder has a head 25 formed with a plurality ofpoints, Figure 3, to prevent the pike entering the pole 26 too far.

The operation is obvious. The advantages are that the tube or cylinder24 is in exact longitudinal alinement with the bar 1 so that there is notendency to lateral strain; that the cylinder acts as a guide for thebar and prevents any tendency to buckle at the joint; and that the barmay be turned axially'at any time so that the lever 5 may be operatedfrom any angle.

It will be noted that no extra parts are needed and that the sectionsmay be separated or assembled without removingV a single screw or bolt.

l claim as my invention:

1. ln a pole pusher, two telescoping sections in longitudinal alinement,the upper section to engage a pole and consisting of a cylinder, and thelower section to be anchored tothe ground and comprising abar projectinginto said cylinder, and a runner movable on said bar and constituting aseat for said cylinder.

2. A pole pusher comprising a bar,v a runner movable on said bar, a seatcarriedA by the upper end of the runner, and a cylin drical memberresting on said seat and into which said bar projects.

3. A pole pusher comprising a bar, a runner movable on the said bar,means moving said runner step by step on said bar, the upper end of therunner having a seat, a cylindrical member removably supported in theseat and into which extends the upper end of the bar. y

4. A pole pusher comprising a bar, a runner movable on said bar, meansfor moving the runner step by step on said bar, a foot Jfor the lowerend of the bar, and a cylindrical member having a pointed up per end,and a seat carried by the upper end of the runner adapted to removablysupport the lower end of the cylindrical n'lelnber yand. said barextending into said cylindrical member.

5. A pole pusher, comprising an I-bzu', L runner movable 011 said bar,means for moving the runner step by step on said bar, a foot for thelower end of the bar, a cup-shaped seat carried by the upper end of therunner, und u cylindrical tube ol an interior diameter to receive the-bur whereby the tube s held against any twisting action on the bur andis free to move longitudinally thereof,

In testimony whereof l have signed this speeiicaton.

PHILP J. HARRAH.
